1) A woman that sleeps around. A lot. A dick-dock because she lets all penises land in her port. And by port, we meanvagina. Somewhat similar to a delivery truck entrance to a store, in that there is constant loading and unloading in the dock. She's hot, but if you sleep with her you'll just be another notch in the post. And probably get a disease.

2) A word that rhymes with tick-tock. Used as a triple-tonguing exercise for wind instrumentalists. Said as "dick-a-dock"
